Cutting apparatus and printer

Abstract

The disclosure discloses a cutting apparatus including a feeder, a fixed blade, a movable blade, and at least one scraping-off device. The movable blade is configured to slide in a sliding direction crossing a transport direction against the fixed blade and is configured to move along the sliding direction from a standby position on one side to a cutting position on the other side and to cut the print-receiving medium fed by the feeder. The at least one scraping-off device is disposed in proximity to the movable blade and is configured to come into contact from the other side with an adhesive that has adhered to the movable blade and scrape off the adhesive when the movable blade moves from the standby position on the one side to the cutting position on the other side.

What is claimed is: 
     
       1. A cutting apparatus comprising:
 a feeder configured to feed a print-receiving medium including an adhesive layer along a predetermined transport direction; 
 a fixed blade having a shape like a flat plate; 
 a movable blade that has a shape like a flat plate and is configured to slide in a sliding direction crossing said transport direction against said fixed blade and is configured to move along the sliding direction from a standby position on one side to a cutting position on the other side and to cut said print-receiving medium fed by said feeder; and 
 at least one scraping-off device that is disposed in proximity to said movable blade and is configured to come into contact from the other side with an adhesive that has adhered to said movable blade and scrape off said adhesive when said movable blade moves from the standby position on the one side to the cutting position on the other side. 
 
     
     
       2. The cutting apparatus according to  claim 1 ,
 wherein said at least one scraping-off device comprises an extension part that has a shape substantially like a flat plate and is disposed downstream from said movable blade in said transport direction to face said movable blade, and 
 wherein said extension part includes a slope part that is formed on an end portion on the one side and is inclined in a manner that the more a portion of the slope part is positioned in the one side, the more the portion of the slope part comes closer to said movable blade. 
 
     
     
       3. The cutting apparatus according to  claim 2 ,
 wherein said movable blade has a substantially V-like shape in a view from said transport direction, and 
 wherein said extension part has a rectangular shape elongated in an orthogonal direction orthogonal to said sliding direction in the view from said transport direction. 
 
     
     
       4. The cutting apparatus according to  claim 2 , wherein when said movable blade is at said standby position, the end portion of said extension part on the one side is located at a position lower than an end portion of said movable blade on the other side. 
     
     
       5. The cutting apparatus according to  claim 2 , further comprising an accumulating part that is disposed downstream from said extension part in said transport direction and is configured to introduce and accumulate the adhesive scraped off by said at least one scraping-off device. 
     
     
       6. The cutting apparatus according to  claim 2 , wherein said at least one scraping-off device includes:
 a first scraping-off device disposed upstream from said movable blade in said transport direction; and 
 a second scraping-off device disposed downstream from said movable blade in said transport direction, and 
 wherein said extension part and said slope part are included in said second scraping-off device. 
 
     
     
       7. The cutting apparatus according to  claim 1 , wherein said at least one scraping-off device also serves as a guide part configured to guide a feeding of said print-receiving medium by said feeder. 
     
     
       8. A printer comprising:
 a cutting apparatus; and 
 a printing head, 
 wherein said cutting apparatus comprises:
 a feeder configured to feed a print-receiving medium including an adhesive layer along a predetermined transport direction; 
 a fixed blade having a shape like a flat plate; 
 a movable blade that has a shape like a flat plate and is configured to slide in a sliding direction crossing said transport direction against said fixed blade and is configured to move along the sliding direction from a standby position on one side to a cutting position on the other side and to cut said print-receiving medium fed by said feeder; and 
 at least one scraping-off device that is disposed in proximity to said movable blade and is configured to come into contact from the other side with an adhesive that has adhered to said movable blade and scrape off said adhesive when said movable blade moves from the standby position on the one side to the cutting position on the other side, and 
 
 wherein said printing head performs printing on said print-receiving medium fed by said feeder. 
 
     
     
       9. The printer according to  claim 8 ,
 wherein said at least one scraping-off device of said cutting apparatus comprises an extension part that has a shape substantially like a flat plate and is disposed downstream from said movable blade in said transport direction to face said movable blade, and 
 wherein said extension part includes a slope part that is formed on an end portion on the one side and is inclined in a manner that the more a portion of the slope part is positioned in the one side, the more the portion of the slope part comes closer to said movable blade. 
 
     
     
       10. The printer according to  claim 9 ,
 wherein said movable blade of said cutting apparatus has a substantially V-like shape in a view from said transport direction, and 
 wherein said extension part has a rectangular shape elongated in an orthogonal direction orthogonal to said sliding direction in the view from said transport direction. 
 
     
     
       11. The printer according to  claim 9 , wherein when said movable blade is at said standby position, the end portion of said extension part on the one side is located at a position lower than an end portion of said movable blade on the other side. 
     
     
       12. The printer according to  claim 9 , wherein said cutting apparatus further comprises an accumulating part that is disposed downstream from said extension part in said transport direction and is configured to introduce and accumulate the adhesive scraped off by said at least one scraping-off device. 
     
     
       13. The printer according to  claim 9 , wherein said at least one scraping-off device of said cutting apparatus includes:
 a first scraping-off device disposed upstream from said movable blade in said transport direction; and 
 a second scraping-off device is disposed downstream from said movable blade in said transport direction, and 
 wherein said extension part and said slope part are included in said second scraping-off device. 
 
     
     
       14. The printer according to  claim 8 , wherein said at least one scraping-off device of said cutting apparatus also serves as a guide part configured to guide a feeding of said print-receiving medium by said feeder.
